TR300D rotary drilling rig is new designed sell-erecting ig mounted on original Caterpillar 336D base adopts advanced hydraulic loading back technology integrates advanced electronic control technology, which makes the whole performance of TR300D rotary drilling rig each advanced world standards.
TR300D rotary drilling rig is specially designed to suit the following applications:
The TR300D is mounted on an original Caterpillar 336D base chassis and is powered by a high-performance SCANIA/CAT turbocharged engine, ensuring excellent stability and load matching under variable construction environments.
It features a maximum drilling diameter of 2500 mm and a maximum drilling depth of 56 meters (interlocking Kelly bar) or 84 meters (friction Kelly bar).
The rotary head utilizes an advanced three-level anti-shocking technology designed to efficiently absorb kelly bar impacts, while its REXROTH or LINDE motor adapts output torque dynamically to geological conditions.
The TR300D implements a newly designed winch drum structure that actively prevents steel wire rope tangling, significantly extending the service life of the wire rope.
The TR300D is ideal for drilling with telescopic friction or interlocking kelly bars, cased bore piles (driven by rotary head or casing oscillator), continuous flight auger (CFA) piles, and displacement piles for soil-mixing.
Equipped with Pal-fin auto-control electric systems, the rig includes an electronic leveling device that monitors and automatically adjusts the mast, ensuring absolute verticality throughout construction tasks.
